Use PROJECT_VERSION instead of CMAKE_PROJECT_VERSION when setting the
version of a qml module, which extracts the version of the latest
project() call rather than the top-level one.
Using CMAKE_PROJECT_VERSION caused issues in top-level builds where
the qtdeclarative version is 6.2, but the top-level project version is
still 6.1 and hasn't been updated to 6.2, causing qml module import
errors.
This was probably an oversight during initial implementation of qml
support in pro2cmake.
So projects that define qml modules should be adapted accordingly.
